利用dsp builder设计的IIR滤波器，已经验证完全可以使用，只需要把其中系数改变。内含VHDL代码(Design IIR filters by dsp builder have been verified , just change the coffetions including VHDL code.)

提供了利用 GPIF 对 FX2LP 与同步 FIFO CY7C4625-15AC 之间的接口进行设计的源代码(Provides for the use of GPIF FX2LP and synchronization FIFO CY7C4625-15AC to design the interface between the source code)

–ABCDE五路输入表示五人的选择，同意为1，不同意为0，以开关形式实现 –有半数以上同意绿灯亮，否则红灯亮。即分别对应输出Y、R为1或0 –参考仿真结果图：10ns|20ns|30ns|40ns|50ns

基于fpga的DDS程序 可输出正弦波 方波 三角波 锯齿波(DDS program based on FPGA can output sinusoidal square wave triangular wave sawtooth wave)
